Under Windows (English), you could delete the files C:\Documents and Settings\\Application Data\OpenOffice.org2\user\registry\data\org\openoffice\Office\Recovery.xcu and C:\Documents and Settings\\Application Data\OpenOffice.org2\user\registry\cache\org.openoffice.Office.Recovery.dat along with the entire contents of C:\Documents and Settings\\Application Data\OpenOffice.org2\user\backup\ The path names may be different under a non-English version of Windows, and under Linux, these files will be located in a subdirectory called .openoffice.org in your home directory. EDIT: Deleting Recovery.xcu will reset the autosave interval back to its default value of 15 minutes. This can be changed under Tools | Options | Load/Save | General.
